BUTTON-FASTENER FOR .AUTOMOBILE-CURTAINS. I

Specicaton of Letters Patent.

Patented Dec. l5, 1908.

Application filed December 18, 1907. Serial No. 406,979.

T 0 all whom it may concem.'

Be it known that I, ALFRED Bnssn'r'rn, a subject of the King of England, residing at Holyoke, in the county ot' Hampden and State of Massachusetts, have invented new and useful Improvements in Button-Fasteners for Automobile-Curtains, of which thc following is a specication.

This invention relates to improvements in curtain fasteners or buttovns, and is particularly designed for securely holding 1n place. the curtains of automobile tops, the`object of the invention being to provide a device that is simple in structure and one that is strong and easily operated to fasten and unlasten the curtains ol an automobile, or for other similar uses.

In general, thc invention consists in securing a rotatable member to a fixed member and with means located between the two members for adj ustably locking the rotatable member so as to register with an opening or button-hole in the curtain piece, or to stand transversely of the ope1iing,'said men ns perv mitting the rotatable member to be yield ingly moved from either position upon an excess 'of ressure against the locking means.

In the rawings forming partof this application,-Figure l is a pla-n view of a portion of a curtain showing in full lines the rotatal'ilo member in register with the button-holo, and in dotted lines located trnnsi'ierscly ol' said button-hole. Fig. 2 is a side elevation of line 3;-3 of Fig. l showing thc locking moans in detail. Fig. 4 is a longitudinal sectional view on the line 4-4- of Fig. l showing the rotatable member transversely located und in locking position. Fig. 5 is a detail perspective view of the under side of the rota* table member showing the recesses for eni gaginf the locking means.

Reierring to the drawings in detail, (L designates a iixed member to which is secured the plate b by means of the screws c. Secured to the plate b is a member d by means of the screws e; this member is diamond-shape in plan View, although I do not limit myself to any particular forni.

fdcsignatcs a button member that is rotaare adapted to engngc the sockets or de-` pressions y11n-there being'l'our ol them, as clearly shown in Fig. ffentl when the spring-pressed ballsengage these de iressions, thc rotatable member is held fixed in either a locking onunloeliing position but will lendilv yield. upon rotary pressure being 'exerted thereon b v the operator.

i The curtain element nis i'nfovidod with 'a `button-hole o inningr o that is sii'nilar in shape tol the roiata )le locking element f'so tha'it when the curtain is placed over` the lookin" element und into,engagement with theiixed member (l, and the button rotated, thc'i-.ur-

tainfaill be securely locked to its support, ns

clearly shown in Fig. l. :und held in ,this position by means olf the halls 'It engaging the recesses m. 'l`o un'l'asten the curtain clement, it is simply necessnryy to reverse the operation. i

As an improvement' `in fastening devices having in combination, n suitable 'sup ort, a member, :als (l, secured thereto, a utton .membciy nsf, and means including a screw,

as g, rotatably mounted in seid member, the button member having recesses on the under side thereof, and means including elasticelementsY mounted 1n said member, as y,

balls7 as lc, engaged by the elasticelements,

`for normally engaging the recesses on the under side of the rotatable member, as described.
